A Numerical Study on Effect of a Partition Wall Height on Wind Pressure Load when KTX passes through a Station

한국고속전철(KTX)이 역사를 통과할 때 격벽의 높이에 따른 풍하중의 변화에 대한 수치해석 연구

A high speed train passing through a station may have undesired effects to passengers on platform due to abrupt pressure transients. Therefore it is very important to reduce the possible degree of danger by installing partition walls in passing lanes in designing the stations having passing train. In the present study, a pressure load to a passenger on platform is studied for the cases of various heights of the partition wall to assess the effectiveness of the wall on the passenger safety. From the results, it is seen that the pressure load on a passenger may be largely reduced by the partition wall. The heights of the partition wall for various passing speed are also studied based on the safety regulation.
